"And the Germans once stood in terror of our great Vikings, who lorded it over the seas in every direction!" added Valdemar, with growing enthusiasm. "Their graves may be seen on both sides of the North Sea to-day. And wasn't it here, Uncle Thor, when an unusually severe winter had bridged the Baltic, that the Swedish king, Karl Gustav, led his army, horse, foot and guns, over the frozen seas where no one had dared to cross before, and finally took Copenhagen? But Denmark and Sweden are at peace now."

"I'm glad that they are," replied Karl, "and that Norway and Denmark are, too, or we might not see King Haakon next Monday!"

"Come!" said Uncle Thor. "Let us hurry home now, before we are late to dinner. It is a wonderful old tower, having survived both fires and bombardments. Once Copenhagen was fortified with a wall and a moat, for Denmark's capital has passed through many vicissitudes, but in these peaceful days they both have been turned into parks for the people."

Dinner had been awaiting the hungry sightseers for some time when they reached home.

When they had all gathered about the dinner table, it was plain that there was some great secret in the air. Fru Ingemann's face wore a bright smile, in spite of the late dinner, and little Karen held herself with an air of supreme importance, her cheeks bright, and her blue eyes dancing with suppressed excitement.

"Great news, Brother Thorvald!" began Fru Ingemann, handing him a great white envelope bearing the arms of His Majesty, King Frederik. "When Karen and I were quietly studying the recipe book, and thinking of the dinner far more than of kings, the bell rang sharply, and, lo and behold! there stood the King's royal Jaeger[17]—in green uniform, three-cornered hat and all—inquiring for you, brother!

"'His Majesty, the King, sends this message to Hr. Professor Svensen,' he said with a gracious bow, and, again bowing low, departed. Karen and I, as you can well imagine, have been guessing everything possible and impossible ever since, and given up in despair, waiting for you to explain it all to us yourself, Thorvald."

By this time, Valdemar's and Karen's eyes were bulging wild with curiosity, and even Mr. Hoffman's face showed extreme interest. What could it be?

"I am summoned to the Royal Palace Tuesday at eleven o'clock," explained Hr. Svensen, "to begin immediate work upon a statue of His Royal Highness, the Crown Prince Olaf of Norway, who has graciously consented to give me a few sittings during his short visit in Denmark."
